L Band Wavelength Tunable Laser Module
The TWL-L-B-M is a wavelength tunable laser module in L band based on integrable tunable laser assembly (ITLA). TWL-L-B-M alleviates inventory and sparing costs in high-channel-count DWDM systems by allowing a single device to replace each of the single-channel devices. Full-band tunable assemblies also enable system functionality such as hot back-up and dynamic provisioning in addition to applications of optical regeneration and wavelength conversion. The TWL-L-B-M has a low Relative Intensity Noise (RIN), a high Side-Mode Suppression Ratio (SMSR), a narrow linewidth, and excellent wavelength accuracy. Its RS232 control complies to OIF ITLA Multi Source Agreement (MSA) standard. A GUI software is provided for easy control of the wavelength and optical power. The TWL-L-B-M can be used for Dense Wavelength Division Multiplexing (DWDM) optical transceivers and DWDM discrete line card designs.
